To all whom it mow-acorn:

vBait known that I, JAMES'S. ANDREWS, a citizen of the'United States, residingatN'ew York ci in the county of New York-and State of New York, have invented new and useful Improvements in Um'lerframes for Cars, of which the following is aspecification.

This inventionrelatesto underfrarnes for railway car's, its object being rimarily to provide a lnetal-underframeo strong and substantial construction and composed =01": standard section's consisting of steel castings securely fastened together.

The invention also has'ior its object specifically to'provide irn iroved. means of sun le constructionadapted to be easily applied 'or securing and holdingthe sectionsof the untlerframe' rigidly-to each other.

.As the invention relates .more especially to the .mann'er and means ifor 'securing the castings forming the underfr-ame togetherit Will-'bBHIIIdBF-StOOd of course that'the invention can be embodied in underframesofvarinus constructions and therefore '11 do not 5 llimit myself to the adaptation-of the:invention .with the particular construction 1 cf 11n- .-.derframe illustrated in the accompanyirrg drawingain which Figure 1 is a top plan =view oi .an.under'-' -i'rame.embodyingjrnynnvention. -F-i-g. 2 is an enlarged detail inside elevationofone-cf :the joints between .the center sill and the draw-ban sill. Fig. 3is'anenlarged detail in- --side= elevationzicf one 'of' the joints in the'side "sills. -.Fig. e is an'enlarged detail plan'--vie'w, partly broken away and in section, ofone of the i'joints between the center -.sill and the draWi-bar-sill asishownz in Fig..2. Fig. :5 is-a similar viewof one of the joints in the side sills as shown-in Fig. 3. Fig. 6 is a top plan view; partly broken away andiin-sectron, of the joint between the draw bar sill; and oneof the side sills. Fig. =7 :is :an enlarged top plan view andF' 8 is an inside elevation of one of the joints inthe end sills; Fig.9 is an inside elevation of one of the joints'in the bod bolsters." Fi 10 is a sectional view on the ine 10-10 of ig. 1 and Fig. 5. Fig. 11 is a sectional vie'won the line 11-11 of Fig. 530 1 and 4. Referring consist of two end sections 7 and'a central sect'on 8,. these sections bein all preferably made of cast steel in channe forniknnd ri 5' 5 idl securedtogether at their adjacent on s as hereinafter described. At each end of the inclined.

to the drawings, the side sills frame is a draw-bar sill 9 suitablyforlncd-to receive the draw bar and .its attachments. The draw-bar sills are each provided with side projections -10 r to abut .atgainst -side=project'ions 11 on the side sills an form the-body bolster and also with side projections 12 -to abut againstside projections 13 nthe side sills to form the end sill. The'draw bar sills :fianges which provide achannelon one or both-sides of "the joint and ithe-channel is made in a: proper form at the joint to-receive the -wedge plate and corresponding substantially'to the shape=thereo Thechannelat the joints and the wedge plates are made -sub' stantially in the customary form of a wedge, smaller at one-end than at the other, although both sides of the wedge, that is to say the flanges, :are "not inclined, the t'op flange being orizontal and the lower-flange A wedge plate It (Fig. 2)'overlaps'the joint b'etween the center sill section 15 and the draw-bar sill 14 andthis wedgeplateis :made inich-annel form to fit 'between'=the :flanges of the sections. .The wedge-plate '16 has a'ztop fiange lfianda bottom fiangel'fi .tto ageithetopfiangestflfi andithe' botan cs 14'', 15" of the-sections .1 4, I5,-

tom the. top anges being horizontal and the bottom: flanges mclined,.-as clearly shown-imFig.

.2. 2A wedgei'plate 17 (Fig; Fi l-similar in form "to: the wedge'plate l6 butproportioned tofit the parts is arranged in. a similar manner at each joint in the side sill. Wedge plates 18,

, 19 (Figs. 8, 9) are arranged in the joints in the end sills and body bolsters respectively, these wedge plates being properly pro ortioned and shaped to lit the parts for w ich the are made.

e wedge plates are all preferably made i inchannel form and are slipped into place and then driven longitudinally and tightly into locking position overlapping the joint between the sections and between the flanges of said sections. Then the wedge plates are fastenedto the sections by bolts 20. The projections on the draw-bar sill and on the side sills which form the body bolsters, and

the center sill projections 14 and section 1 5, are made in I form and therefore I prefer to provide a wedge plate in the channel on each side of the joints in the body bolsters and the center sill, and the two wedge plates at each joint may be fastened together by transverse bolts passing through the sections, as shown gin Fig. 11. As the side and end sills are preferably made in channel form I prefer to provide a flat face plate 21 overlapping each joint on the outerside thereof and also fastened bybolts passing through the sillsto the wedge platejon-the inside of said joint (Fig. 10). To accommodate the face plates 21 the flange 23' on the side sills, which is provided to support some of the timbersof the car,

cut away at 24 (Fig. 1). Flat face plates 22 are alsobolted to thetop and bottom of'th'e sections and overlapping the joints.

I preferto locate the oints in the side sills out of alinement-with the joints in the center sill and for this reason I have shown the joints in the center sill close-to the body bol-J. stersiand'atsome distance from the j oints' in the side'sills. i

Asnheretofore mentioned the sections of the underfranie may he made in any desired form and number so-far as my preser'it" 1-nven- I -t1on .1s concerned, and theg olnts can be. lo-

cated wherever preferred' The invention facilitates. the operation of assembling the sections of the underframe and the plates at the=jointscan be readily removedto' permit.

- the removal of anysection for" repair or-reg placement without disassembling "the, entire frame.

ters Patent is:

1. In asectional underfranie forcars, the

combinationof'two sections arran ed end to end and provi ed with a side" 0 annel ,at

than at the. other secured in said channel and their abutting-ends larger at one end than at the other, land a" tie platelarger at one end overlapping said ends. 2.111 a sectional underf rame for cars, the combination of two sections arranged end to endand .provided with aside channel at their abutting ends, said channel being tions to secure all the parts together.

5, v1n a sectional underfram'e for'cars, the

4. In a sectional underframe for cars, the

, combination of two sections arran ed end to end. and provided with a' side 0 annel at their abutting ends, said channel being wedge shaped longitudinally, a wedge plate secured in said'channel and overlapping said ends, a flat face plate overlapping saidends on the outer side thereof, an fasteningv de-' vices passing through said plates and sec- .combi'nation of two sectionsarranged end to end and. provided with a; Wedge shaped channel on one side thereof at their ends, a wedge platesecured in 'said channel, a flange on the outer side of said sections, said flange being cut away at the. joint, and aface plate secured to thesections over the joint and in the-cut-away part of the flange.-

' 6. In an nnderframe for cars, the combi' nation of a plnralit of sections made toQfit to ether an provi ed with a wedgeshape d si e channel at each joint,and wedge shaped channel plates secured in said channels and overlapplng the joints.

'7; A sectional-underframe for cars com-. I

prising two side sills each consistingofgtwo endsections and a middle section arranged end to-end and secured together, two drawbar sill sections, and a center sill section se cured at its ends to the draw-bar sill sec? tions, the joints at the ends .of the center sill section being, located intermediate of the ends of the end sections of the side sills.
